What This Code Means

A systemic form of childhood arthritis that affects the whole body with fever, rash, and joint inflammation, but the specific affected joints are not documented.

Coding Tips

  • This code indicates systemic onset juvenile rheumatoid arthritis without specification of which joints are involved
  • Document systemic symptoms such as fever, rash, and lymphadenopathy to justify this diagnosis

Clinical Significance

Systemic onset juvenile rheumatoid arthritis with unspecified site represents the most severe form of pediatric inflammatory arthritis with systemic manifestations including fever, rash, and organomegaly. This condition has the highest morbidity risk among JRA subtypes and requires intensive immunosuppressive therapy.

Documentation Requirements

  • Physician diagnosis of systemic onset juvenile rheumatoid arthritis
  • Age of onset documented as under 16 years
  • Evidence of systemic features (fever, rash, organomegaly)
  • Laboratory evidence of systemic inflammation
  • Documentation of arthritis component
  • Assessment of systemic organ involvement
  • Treatment with systemic immunosuppressive therapy
